What is wrong with the PSP-Games?

[DirtyP2002]

Hey,

 

I am just wondering why the PSP just can't sell games. There are only 5 games in the worldwide top 100 this week. The best one is placed on No. 38! The DS sells so much more. I know the userbase is bigger, but not that much bigger in relation to the gamesells.

Could u please give me some thoughts about it. I just don't get it. Nearly 36 million PSPs are sold, there should be some software moved.
